Introduction

This example will run a circle (size:100x100) filled in reverse way.

There are 10 cells with :

active-color = #FF0000 (red)
inactive-color = #000080 (navy)
spacing = 0

Percent text info is right aligned on a 100 pixels width area, at right side of circle.

PHP script

Build the progress bar

require_once 'HTML/Progress.php';

$bar = new HTML_Progress(HTML_PROGRESS_CIRCLE);
$bar->setAnimSpeed(100);
$bar->setIncrement(10);

$ui =& $bar->getUI();
$ui->setfillway('reverse');
$ui->setStringAttributes('font-size=20 width=100');
$ui->setCellAttributes(array(
    'width' => 100,
    'height' => 100,
    'spacing' => 0,
    'inactive-color' => 'navy',
    'active-color' => 'red'
    )
);
$ui->drawCircleSegments('temp', 'cb%s.png');

Loop to run the progress


do {
    $bar->display();
    if ($bar->getPercentComplete() == 1) {
        break;   // the progress bar has reached 100%
    }
    // your user-process should be put HERE !
    $bar->incValue();
} while(1);
